Abstract: 1372906 Analogue to digital converters COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 15 Nov 1972 [17 Nov 1971] 52806/72 Heading G4H In an analogue to digital converter the input signal is cumulatively doubled in successive clock instants by an amplifier 12 having a gain of 2 and a recirculating loop having capacitors Cl, C2 which are alternately charged by the amplifier output and discharged into the amplifier input until a positive or negative threshold +Vr or -Vr is exceeded as detected by comparators 13, 14, a binary counter 24 being decremented from a starting value of 111 for each such doubling to obtain the 3 most significant bits of the code, the next 4 bits being entered into a shift register 26 during the next 4 clock instants as the result of further doublings of the difference between the already cumulatively doubled input signal and a reference signal generated by 19 or 20 each time a respective threshold -Vr, +Vr is exceeded. The sign is stored in flip-flop 28. The input attenuator 11 halves the input signal. In a modification, Fig. 2 (not shown), three doubling and recirculating loops are connected in series.

Title: Printer and control lcircuit therefor
IPC: G06K15/06
Filed: 1970-01-29
Abstract: 1331953 Printers MOHAWK DATA SCIENCES CORP 6 Nov 1970 [29 Jan 1970] 52950/70 Heading G4H In a printer, a plurality of printing mechanisms are energized by a single driving circuit connected to them in turn. A type drum rotates about an axis parallel to the print line, the characters approaching print position being indicated by a coded disc rotating with it, the disc indications being compared with the characters to be printed in turn to produce a fire pulse for each print column in turn. A clock-driven flip-flop gates the fire pulses to two hammer drivers alternatively, these drivers relating to odd and even print columns respectively. An odd hammer select circuit routes each output pulse from the odd driver to the actuating coil of the appropriate hammer, these coils being arranged in a matrix, two groups of stages of a clock-driven counter being decoded to select a row and a column of the matrix respectively thus selecting a coil at the cross-point to receive the driver output. An even hammer select circuit is similar. The counter in each hammer select circuit is incremented by a clock pulse while the other hammer select circuit is in use, under control of the flip-flop.

Abstract: 1306319 Valves ROBERT BOSCH GmbH 17 Nov 1971 [17 Nov 1970] 53291/71 Heading F2V A pressure regulating valve comprising a hollow cylindrical valve member 3 slidable in a housing 1 against the action of a spring 10 and provided with a throttle portion 6 and at least one orifice, as at 7 forming communication between an inlet port 5, the interior of the member, an annular chamber 8 formed in the housing and an outlet port 9 is provided with damping means comprising a cylinder member 15 movable with said valve member relative to a piston 17 disposed in said cylinder member to form a damping chamber 21, said means being so constructed that the valve member is weakly damped when moved in the direction to reduce the flow of pressure through said valve and strongly damped when moved in the opposite direction. The degree of damping can be regulated by altering the width of the gaps between piston-rod 18 and the box 19a, and between the piston head 17a and the cylinder 15. Openings 16a in the flange 16 release pressure in the chamber 2a during the weakly damped movement. In further embodiments a sleeve with a longitudinal groove in its inner surface is positioned in the chamber 21 and held against the head 17a by a spring 25 to further increase the damping. The head portion of the piston may be made of resilient material and be provided with an annular lip to act as a non- return valve. The pressure medium in this case returns to the main valve chamber via a throttling orifice provided in the cylinder 15 and the openings 16a.

Abstract: 1498182 Fade-out control for cine camera AGFA-GEVAERT AG 16 Dec 1974 [15 Dec 1973] 54316/74 Heading G2E Stepping motor 13 driven by pulse generator 12  opens or closes the diaphragm 15 to give both an automatic exposure control and a fade-in/fadeout. Photo-detector 2 situated behind the diaphragm acts with resistor 3 as one arm of a bridge circuit, the other arm 6, 7 supplying a reference voltage to amplifier 8. Here it is compared with the voltage at 2/3 and unbalance is corrected by appropriate movement of stepping motor 13 and diaphragm. By switching in a further resistor 4, a fresh zero position is set up and this corresponds to gross underexposure of the film. Fade-out time is obtained by the transition from the normal setting to the new setting. After re-winding the film, switch 5 is opened and the new scene fades in.

The holder is provided with ribs 46 to grip the stopper and hold the con- :ainer at an appropriate position within the holder. A circumferentially extending rib 48 within the holder serves is an indicator of the position of the end of he cannula in the stopper when the top of the stopper is aligned with t. To withdraw blood, end 26 of the cannula s inserted into a vein, end 32 of the cannula being embedded in the stopper. The container s then pushed to its fullest extent into the holder. When full, it may be retracted to the position at which the top of the stopper is in alignment with rib 48 or it may be entirely withdrawn from the holder, followed by withdrawal of end 26 of the cannula from the vein. The assembly, or parts thereof, may be packed in sterile packages. The container and holder are generally transparent. The latter may be made of polypropylene.

Title: Pulse motor driven circuit
IPC: G04G3/02
Filed: 1973-11-30
Abstract: 1451359 Electronic timepieces CITIZEN WATCH CO Ltd 30 Nov 1973 55634/73 Heading G3T [Also in Division H2] An electronic watch driven by a stepping motor is provided with means for correcting the position of the second-hand by the application of a train of high frequency pulses to the motor in a direction depending on whether the hand is leading or lagging from its correct position at 0 (60) position. The correcting pulses are at 64Hz and the driving pulses are at 1Hz and so the correcting operation does not affect the normal operation of the motor. Two counters count up and down the input pulses to the motor, there being gates joining the up counter with the down counter to ensure that in normal operation they always show the same count. When correction is required a switch is operated to open the gates and the up counter is connected to a logic circuit and a flip-flop gate device which provides an output indicating whether the count is in 0-30 or 31-59 ranges. Depending on this signal the fast pulses are applied in one of two orders to move the second hand to the zero position in one or other direction and to enable either up or down counters to count these pulses. The train is terminated when either counter reaches zero. Logic circuitry comprising e.g. a 0-4 counter enables one of 4 sets of gates according to its count to ensure the pulse order of the correcting pulses is in phase with the motor position.
